Superintendent Training - Lesson 8 Mechanical Rough Subcontractors Heating-Plumbing-Electrical Preparation 1. Reserve Conference Room 2. Make _____ Copies of this Lesson Plan for Personnel 3. Make Transparency, procure transparency pens, etc. 4. Coffee, tea, snacks Other: Material 1. Subcontractor Checklists 2. 100 Day Construction Timeline (for reference on how long it should take each subcontractor to do their phase) 3. Other Objective By the end of this session, personnel shall be familiar with:  1. Heating Subcontractor Job Scope and Checklist  2. Plumbing Subcontractor Job Scope and Checklist  3. Electrical Subcontractor Job Scope and Checklist Background Once the framing subcontractor has the interior walls framed, roof decked and stairs set, and the siding subcontractor has begun, the three mechanical subcontractors should begin their phase of work, one at a time. Normally, the heating contractor is the first mechanical trade to begin in a newly constructed home. This is because his duct work is more bulky and less maneuverable than the plumber's pipes or the electrician's wires Page 1 of 7 .............Notes............ . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

Lesson Heating Subcontractor Job Scope and Checklist You should arrange a brief meeting between the heating and plumbing contractors, so that they can discuss the home as it relates to them. They should discuss where the wall stacks will be, and which floor joist spaces would best accommodate each subcontractor. The heating contractor will supply all permits, labor, and materials to provide heating and air conditioning services to the home. He will provide all:  1) Furnaces, duct work, combustion air, and plenums  2) Air conditioning condensers, coils, and condensate lines  3) Furnace and water heater flue piping  4) Registers and grilles  5) Roof jacks and storm collars  6) Laundry chutes  7) Thermostats (permanent and temporary)  8) Bath vents and duct work  9) Dryer vents, duct work, and all exterior heating hoods  10) Range hood venting  11) Heat runs to all plumbing water lines and tub traps susceptible to freeze up (in exterior soffits, garage ceilings, exterior walls, crawl spaces, etc.)  12) Temporary metal covers over cut-in floor registers  13) Structural straps over cut-out top framing plates  14) Fire-stopping flue chases  15) Insulation for duct work and A/C condensate lines The Fireplace Installer should install the fireplaces during this stage of construction, provided that the hearths and flue chases are built Go over the attached check list with the Heating Contractor for his input. .............Notes............ . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

Electrical Subcontractor Job Scope and Checklist When the Heating and Plumbing subcontractor have finished, the framer should return to the home, and do his back-out BEFORE the electrician starts. Framing back-out is a term used when the framer installs all drop ceilings, soffits, fire-blocking, stair way walls, basement floating walls, chases around heat and plumbing stacks, furring strips in the garage and elsewhere, and all final framing. The framer also repairs whatever was disturbed or damaged by the heating and plumbing contractors. Before the electrician can begin work, in most municipalities, the roof covering (shingles, etc.) must also be completed. Check with the municipality before you schedule the electrician! Some municipalities also require a licensed electrician to be on the job site and a separate electrical permit to be pulled. Ensure this happens if it's required. The Electrical Subcontractor will provide all permits, labor, materials, and electrical fixtures and components (meter housings, breaker panels, etc.) to adequately wire and trim out the home to meet all electrical inspections for the home. When the Electrician finally begins, he will normally mark the walls with switch and outlet locations according to the electrical plans you provided him. Let him know of any extras- air conditioning, whole house fans, extra telephone jacks, television outlets, etc. He'll also install the outlet and switch boxes, and may begin to drill out the first day. After the home is drilled out, the electrician will then begin to pull wire. No other contractor should be in the home when the electrician does his work. (The Plumber and Heating subcontractor should have completed their work) They could accidentally nick or burn wires. This is a big a safety hazard! The electrician should mount the electric meter housing and service panel as soon as possible. Once this is done, the electric utility company should be called. The electric lateral should be requested to be ran from the pedestal or transformer to the home service. This can take a month or more once the utility company is otified!
